摘要
本文利用Ｌｉａｐｕｎｏｖ理论，研究了船舶在规则波浪运动的稳性；利用摄动理论，求解出船舶运动响应；并讨论了船舶横摇与垂荡运动频率、最大横摇角和波浪要素对稳性曲线ＧＺ的影响，以及流体动压力对稳性曲线的修正，从而给计算船舶在随浪中的稳性提供了一种方法。
The stability of a ship in following seaway is studied with Liapunov's theory. The motion responses are obtained with the perturbation motheds. And it discusses how the frequency of roll and heaving,maximum angle of rolling and main elements of waves inference the stability curve (GZ),and how GZ is corrected by fluid dynamic pressure, thus providing a new simulated calculation method for ship stability in following sea.
